10. Simple.TV

If TiVo had been invented in the era of web video and cord-cutting, it might have come out looking like Simple.TV. The clever little white DVR, which was successfully crowdfunded by Kickstarter, lets you stream over-the-air HD broadcasts and unencrypted cable TV, in either live or recorded form, to Windows PCs, Macs, iPads and Roku boxes. Those devices can be located on your home network or — as with a Slingbox — anywhere else where an Internet connection is available. Pricing starts at $199; electronic program guide service costs extra, and you provide your own storage for recorded video by plugging in a USB hard disk.
